BT Infinity & FTTx Discussion

They throttle them because they are a nuisance to their other customers that want snappy fast web surfing. That really is both the long and short of it.

Throttle is actually the wrong word. That implies they have set a maximum speed. That's not what is happening. What happens is they are *de-prioritising* the BitTorrent traffic so that it is always at the back of their router's queues. This has the effect of increasing both packet loss and latency for the TCP stream. This then causes the transmitter on the TCP stream to slow down their transmission until it reaches a level that the other side can handle.

You're quite right that no ISP would want to impact upon VPN traffic. Though I can imagine a time will come when ISPs might only honour that if you're on a Business grade package.

Putting a 20Mb service in place through FTTC wouldn't make sense as there are ADSL services that are "up to 20Mb" since years back (even if said services never reach their top speeds, something FTTC by comparison is quite good at). They'd basically do a lot of work for having something that the ignorant mob thinks all ISPs have had for years, even if this isn't strictly true. 40Mb, and certainly 80Mb in coming months and years, makes more sense from a marketing perspective. My two pennies. :).

Probably true, I'm in the unfortunate situation of ADSL MAX being all that is available giving 4-5mbit speeds, with no planned date for delivering LLU, Cable, ADSL2 or FTTC. The theoretical max speed even if you lived next door to the exchange is 8mbit so 20mbit is just a pipe dream.

That said my understanding was the government/EU legislation/thinktanks were supposed to be driving towards a decent speed for everyone rather than a decent average with wide variance between areas.

The way I see it (from a somewhat biased perspective) is they should be rolling out FTTC/P in the internet ghettos not places that already have good services. Putting a 40mbit service in place where I live would make a MASSIVE difference, you'd be talking a 5-10x improvement in speeds. Places with 20mbit ADSL2 and LLU services already in place should be nearer the bottom of the list, not the top, as they already have connections I can only dream about.

Of course, the reality is that big urban areas probably look most attractive because rolling out there means more potential customers than in smaller towns.

you from getting your net cut off (happened to me twice since 2000 by http://en.wikipedia.org/wiki/Energis).
Energis sent me a letter listing EVERY pirated file on my storage drive (including file size, date modified, location), few days later my net was disconnected, luckily they didn't take me to court :)!
Might still have the letters about somewhere, scared the **** out of me at the time. I'd hate to get caught these days.. things are more strict.

Stick to private trackers.

They throttle to prevent stupid bandwidth consumption. It's always going to happen on an "unlimited" service. No way they'll have enough money to invest in bandwidth with each customer paying £25 per month.
 
I think BT are trolling me; had a download on this morning and was getting 9.4 mb/s, just tried another download now and back to 4.4. It's been doing this a lot lately, think I better make use of the spare openreach modem and try get into the stats page!
 
How much better are these faster connections in normal use over say 5mb adsl, do web pages load much quicker, what about web downloads, are they usually limited by the website, what about pings?

Everything is faster. Everything maxes out.

Not sure if serious?

Why?

I know it's faster but im asking how does it differ from a 5mb adsl connection in average use, ignoring quicker downloads with certain things and being better with more users, does it make that much difference?

Is that really true? I was under the impression that you usually get limited web download speeds and page loading times, similarly with video streaming, i sometimes find youtube will need to buffer, how does a faster connection improve this if the limit is with the source?

Well I had ADSL2+ before and even then I found I was getting 2000KB/sec+ download speeds, no YouTube buffering issues at all and web pages generally all loaded pretty quickly, if not pretty much instantaneously.

I guess the point is it depends what you're doing. For me, certainly there seem to be no issues with the sources I download/stream from. The only significant difference I've seen is that instead of downloading at 2000KB/sec, I now get around 4300KB/sec. If I was coming from a 5mbit connection or so then sure, everything would clearly be a vastly superior experience.
 
Hi I currently get this on the copper:

I live about half a mile from the exchange, just wondering will my ping improve with a infinity package?

Yes your ping will improve, depending on where you live in the country, people in or around London get 7ms, I live in central England and get 12ms pings.

Your speed is going to increase by how much depends on the distance to the Cab, most connection receive the full 40mb sync which = to about 37.5mb throughput.
 
Well another weekend is drawing to a close with ****** broadband. BT were supposed to come on Wednesday and install Infinity but low and behold they no showed. Waited in til 1pm (was given a slot between 8am - 1pm) and phoned them - they say there was a problem with installing Infinity because there wasn't a BT line in yet - THE LINE CHANGED OVER TO BT ON MONDAY FFS! They also say they called and explained this to me :confused: :rolleyes: Why bother getting a MAC code and let these incompetent baboons arrange things? My sub par broadband is worse than it has ever been, can't stay stable in any game and can barely browse

Been given next Wednesday as an install date, between 8am and 10am (interestingly, they said it wasn't possible to give such a small window last time) I swear they better turn up, being self employed and taking time out of work means I'm out of pocket. The "adviser" I spoke to said I'd be compensated somehow but couldn't elaborate... I wonder if they will bill me extra for the compensation? :p
